United The present invention relates to new and useful improvements in masonry chisels, particularly for veneer work, and has for its primary object to provide, in a manner as hereinafter set forth, a tool of this character embodying novel means whereby unscribed material may be cut with speed, precision and a minimum of effort.

Another very important object of the invention is to provide a masonry chisel of the aforementioned character which may be expeditiously and accurately adjusted as desired.

Other objects of the invention are to provide a masonry chisel of the character set forth which will be comparatively simple in construction, strong, durable, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a rear perspective view of a masonry chisel constructed in accordance with the present invention;

Figure 2 is a front perspective view of the tool; and,

Figure 3 is a view principally in vertical longitudinal section through the device.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a substantially T-shaped chisel of suitable metal which is designated generally by reference character 5, said chisel including a blade 6 having formed integrally therewith a handle 7.

As illustrated to advantage in Figure 3 of the drawing, the blade 6 has formed therein a threaded opening 8. Welded on the blade 6 in alignment with the opening 8 is a nut 9.

Mounted on the blade 6 of the chisel is a gauge which rates Patent is designated generally by reference character 10. The gauge 10 includes a metallic rod 11 comprising a threaded end portion 12 which is screwed for longitudinal adjustment through the nut 9 and the opening 8. A wing nut 13 is threaded on the end portion 12 of the rod 11 for securing the gauge 10 in adjusted position, a lock washer 14 being interposed between said wing nut and the blade 6.

The rod 11 of the gauge 10 further includes a downwardly inclined end portion 15. Fixed transversely beneath the end portion 15 of the rod 11 is a work-engaging plate 16 of suitable metal.

It is thought that the manner in which the tool is used will be readily apparent from a consideration of the foregoing. Briefly, the gauge 10 is adjusted as desired relative to the chisel 5 and secured in adjusted position by the wing nut 13. Then, engaging the plate 16 with an edge of the material and sliding said plate therealong, the chisel 5 is struck with a hammer or other suitable impact tool for making repeated cuts in said material. Thus, scribing is eliminated and precision and speed are considerably increased.

It is believed that the many advantages of a masonry chisel constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed as new is as follows:

A masonry tool of the character described comprising: an elongated handle provided on one end with a flat surface adapted to receive an impact blow, a transversely elongated blade on the other end of the handle and including a beveled longitudinal cutting edge, said blade having a threaded opening in the central portion thereof, a rod threadedly mounted for adjustment in the opening, a lock nut threaded on the rod for securing the adjustment, said rod comprising an angularly extending end portion, and an elongated, downwardly and outwardly inclined work-engaging gauge plate mounted on said angularly extending end portion of said rod in spaced relation to the blade and parallel with the cutting edge.
